Clinical Utility of WATS3D: A 5-Year Prospective Study
What this study is about
The purpose of this study is to create a registry (collect data and keep it in a research database) to learn more about two methods of taking small tissue samples from your esophagus (the esophagus is the tube that carries food and liquid from your mouth to your stomach).
View original scientific description
The purpose of this study is to create a registry (collect data and keep it in a research database) to learn more about two methods of taking small tissue samples from your esophagus (the esophagus is the tube that carries food and liquid from your mouth to your stomach). The two methods of sampling are: 1) Using forceps that take biopsies (small tissue samples) from your esophagus, and 2) Using a brush that also takes biopsies from your esophagus.
Primary outcome measures
Primary Outcome Measure:
Time frame: 5 years
Clinical Utility of WATS3D as determined by how many patients undergo increased surveillance, radiofrequency ablation and placement on PPIs.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Able to read, comprehend and complete the IRB-approved consent form
- Aged 18 or older
- Meet one of the following:
- Patients with heartburn or regurgitation undergoing a screening EGD, who undergo WATS3D sampling and forceps biopsies for suspicion of BE, or
- Patients with known BE with or without dysplasia undergoing a surveillance EGD with WATS3D biopsies and forceps biopsies, or
- Patients who have undergone endoscopic eradication (i.e. radiofrequency ablation or cryoablation) who are undergoing surveillance EGD following the establishment of complete eradication of intestinal metaplasia (CEIM)
- Only patients who undergo both forceps biopsies and WATS3D of the esophagus will be included.
Exclusion criteria
- Pregnancy at time of endoscopy
- Unresolved drug or alcohol dependency that will limit ability to comprehend or follow instructions related to informed consent, post-treatment instructions or follow-up guidelines
- Medical condition that will likely prohibit completion of a 5 year study

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
